The Lowdown
Alright folks, it’s Rusty here. Let’s be straight with you—this forecast for Kennebunk Beach is a tough one. We’re looking at a whole lot of nothing for the next week and a half, with a couple of small, ordinary windows that honestly aren't going to have you digging the board out of the garage.
The opening stretch is almost a total blank. From Friday the 14th right through to Saturday the 22nd, we’ve got next to nothing. The swell is tiny, mostly under 2ft, and it's coming from the southeast which isn't doing this sheltered spot any favors. The energy in the water is weak, with values mostly in the low teens to seventies. There’s a bit of a pulse on the 20th with 4ft, but the period is a short, weak 6 seconds, so it’s going to be crumbly and won't have any push. The winds are mostly cross or onshore during the day, so you're looking at chop and mess. We do get a few glassy mornings, like Saturday the 15th and Friday the 21st, but with 0.6ft to 2ft of swell, it's just flat. This is a real bust.
The only time this outlook even gets a pulse is on the morning of Sunday the 23rd. For a couple of hours, we might see something. The swell bumps up to 4ft from the east, and the period is a short 7 seconds. The energy is moderate, at 135. But there's light rain and a cross-offshore breeze from the north, which should keep the surface reasonably clean. It’s not going to be memorable, but it’ll be the only thing all week that resembles a surfable wave. Even then, "surfable" is doing a lot of heavy lifting.
After that, the end of the month just fades away again. Monday the 24th drops back to knee-high dribble, and we get a few clean mornings here and there, but the swell never gets going. There's a long-period pulse showing around the 27th with a 13-second period, but it's small and the energy is still just moderate, so it won’t translate into much at this beach break. It's more likely to make things a bit wonky than to deliver any quality.
So, honestly, there’s nothing to get excited about here. The one and only *maybe* is Sunday morning the 23rd. If you’re desperate for a paddle, that’s your window. Otherwise, this is a well-deserved rest week. Forecasts can change, but right now, this is a poor run for the beach.
Rusty.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Kennebunk Beach may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
